Original application filed. June 21, 1915, Serial No. 35,294. Dividedand this application filed February 10, 1916. Serial No. 77,516.

To all whom it may concern:

Be it known that 1, CHARLES RADIGUER, a citizen of the French Republic,residing at St.-Denis, Department of the Seine, in France, have inventedcertain new and useful Improvements in Headers for Boiler Elements; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The present application is a division of my copending application,Serial No. 35,294, filed June 21, 1915, and relates to the constructionof headers or boxes for the elements of water tube boilers. Th presentinvention relates more particularly to the construction of upper headersfor establishing communication between the upper tubes of the elementand the purifier.

The object of the invention is to provide an improved form of upperheader so constructed that as the water and steam are admitted to theheader by the upper tubes of the coils, the currents in the upper headerwill all be directed upwardly, thus insuring a direct path for the waterand steam from the outlet of each tube to the outlet of the header. Bythus directing all of the currents upwardly through the header, thetendency for vortexes to form within the header is eliminated.

The invention is illustrated in the accompanying drawing, in which z-Figure 1 is a vertical section through the improved upper header takenon the line 1-1 of Fig. 2; and

Fig. 2 is a side elevation of the upper header and a portion of theupper tubes of the element connected therewith.

The upper header illustrated in the drawing is designed for use with anelement having four coils, but it will be understood that slightmodifications may be made to the header to adapt it for use withelements of a different number of coils, without departing from theseope of the invention.

Referring to the drawing, the header is denoted generally by thereference character A and is adapted to be connected at a to the pipewhich communicates with the purifier. The header is provided with fourcompartments, indicated at 1, 2, 3 and 4, into which the upper tubes 25,25 t and t of the four coils discharge. It will be understood that thetube t discharges into the compartment 1, the tube 25 into thecompartment 2, i into the compartment 3, and the tube t discharges intothe compartment 4. When the header is used for an element having adifferent number of coils, the number of compartments arranged in theheader will be changed to conform with the number of coils in theelement.

The compartments 1, 2, 3 and 4 discharge into a lateral passage 5through openings 6, 7, 8 and 9, respectively. It will be noted that thecompartments 1, 2, 3 and 4 are formed by the provision of vanes or ribs10, 11 and 12, which are so disposed that they cooperate with theopenings 6, 7 8 and 9 to direct the current from each of the tubesupwardly, as indicated by the arrows in Fig. 1. As all of the currentsin the header are directed upwardly in this manner, the formation ofvortexes within the header is prevented and the passage of the water andsteam through the tubes of the element and through the header to thepurifier is, therefore, made more uniform.

What I claim is 1. An upper header for water tube boiler elements,having ribs extending inwardly and upwardly from one side wall thereofand forming compartments which are open at the top, one end wall of theheader having inlet tube-receiving openings alined with thecompartments, said header having a pas sage with which all of thecompartments communicate, the passa e being arranged between the ribsand the slde opposite to that by which said ribs are carried. p

2. An upper header for water tube boiler elements, having a plurality ofribs extend in g inwardly and upwardly from one side the said headerhaving alateral passage with wall thereof, said ribs cooperating to formwhich each compartment communicates. 10 coniipai-tniilenitls, eiachhopenat its top]; one end In testimony whereof I aflix my signature. wal 0 te ea er aving in et tu e-receiving opening alined with the compartmentsCHARLES RADIGUER the distance of the openings of said com- Witnesses: V
